The more thoroughly it is worked into or infor the improvement or galvanization of iron at high temperatures, there must be aconsiderable volatilization and waste of the-fumes in the state of oxide, &c. These may be collected and saved by vthe employment of suitable rcceirers in connection with the furnace.

Having thus ffully described the nature of myinvcntion, what I claim as new ltherein, and desire to secure by Letters Patent, is-

The application of franklinite to the improvement of iron in the process of reduction from its ores and in the neryor paddling of coarseor pig` iron according to the method as above described.
